Two women had gone out for a girls night out, and had been overenthusiastic on the cocktails. Incredibly drunk and walking home, they suddenly realized they both needed to pee. They were very close to a graveyard, and one of them suggested they do their business behind a headstone.
The first woman had nothing to wipe with, so she took off her panties, used them, and threw them away.
Her friend however, was wearing an expensive underwear and didn't want to ruin hers, but was lucky enough to salvage a large ribbon from a wreath that was nearby and used that.
After finishing, they made their way home.
The next day, the first woman's husband phones the other husband and says, "These girls' nights out have got to stop.
My wife came home last night without her panties."
"That's nothing," said the other. "Mine came back with a sympathy card stuck between the cheeks of her butt that said, "From all of us at the fire station, we'll never forget you!"
